Question

Camels: Camels are desert animals that have pads on the bottom of their feet. The pads are thick and large and help keep the camel stable. They can close their noses to prevent materials from entering. Camels can eat desert plants to gather water. They can go up to 100 miles without needing to drink any water!

The Sahara Desert: The Sahara Desert is made entirely of sand. It rarely rains and is very dry. There are only a few plants, and they have small leaves. The sand is scorching and moves every time it is touched; when the wind blows, the sand shifts in all directions.

How well would a camel survive in the Sahara Desert compared to other organisms, and why?

Answer

When reading the facts about the Sahara Desert and camels, it seems that the organism is perfectly adapted to the habitat. Camels have feet that can walk on the shifting, hot sand, can close their noses during a storm, can go long distances without water, and can eat the desert plants when needed. They have all of the traits or characteristics needed to survive well in a hot, sandy desert.

Question

Amazon Rainforest: In the Amazon Rainforest is rains almost every day. There are very tall trees that create a canopy, and the ground of the forest is covered in plants. The plants on the ground try to grow wide or tall to reach sunlight. The very tall trees can block much of the sunlight.

Bromeliads: Bromeliads grow on tree trunks and branches and wrap their roots around the trees. They need wet habitats to grow well. They have a center portion like a cup or bowl that collects water. Their leaves are waxy, and the water slides into the center. The leaves are long and curved to collect water.

Based on the information provided, how well would a bromeliad survive in the Amazon Rainforest?

Answer

According to the information provided, the bromeliad would survive very well in the Amazon Rainforest. This plant has characteristics or traits that are adapted for survival in this type of environment. It needs a wet environment, and the rainforest receives rain daily. The plant is built like a cup or bowl for collecting water and grows around trees, which the rainforest has plenty of.

Question

In a habitat, all organisms will continue to survive well despite any changes or relocations that may occur.

Answer

This statement is false. Not all organisms will continue to survive well in a habitat if some changes or relocations occur. If an animal is picked up and moved somewhere new, likely, it will not survive at all because it doesn't have the necessary traits to adapt. If a plant suddenly has no sunlight, it will not survive because it cannot make food, which is vital to life. Some organisms may survive well in a particular place, but the outcome may be different if they move or a change is made to the food chain.

Question

Which animal would survive well living in or around a freshwater lake?

Answer

A bass would survive in a freshwater lake because it is a freshwater fish. A stingray, sea turtle, and tuna fish are all found in saltwater habitats and could not survive in a body of freshwater. The bass hunts other bugs and small fish that live in lakes, so it has a food source and the characteristics to survive well.

Which habitat would allow a bromeliad to survive well, and why?

Answer

The habitat that would allow a bromeliad to survive well is a swamp. Bromeliads need lots of water and a wet habitat to live in, a swamp provides this. They also grow by twisting around trees, and a swamp is filled with trees. A swamp would meet the needs of the plant.

Janine says that she believes bromeliads would do well in the Amazon Rainforest, while Natalie thinks they will not do well in that habitat. Who (if anyone) is correct and has an argument that supports their point of view?

Answer

In this specific argument, Janine is correct and supports her argument using relevant evidence from the passage. "Bromeliads would do well in the rainforest because they are adapted to wet habitats, shaped to collect water, so they stay hydrated and grow on trees that are plentiful in the rainforest." is a concise explanation as to why bromeliads would survive well in the Amazon Rainforest. Some organisms will survive well in an environment because they are adapted to the conditions in the area.

Question

Grasslands - The grasslands in the Northern hemisphere are vast, open terrains with flowers and grass. There is enough rain to support small amounts of trees and lots of grass. The soil is thin and dry, and there are often wildfires. The temperatures range from very cold (in the negatives) to comfortable (in the mid-70's).

Which animal would survive well living in a grassland habitat?

Answer

A coyote would survive well in a grasslands area. A coyote would be able to adapt to the type of prey that lives in the area, the weather conditions, and would be able to hunt in the tall grass and trees. A polar bear would not be suited for grasslands because of its thick layer of fat and white fur, it would be too warm for polar bears, and there is no food source for them. Parrots live in tropical climates and high in trees, which grasslands do not have. Panda bears survive by eating bamboo, and there is no bamboo in the grasslands habitats.

Question

Alligators - Alligators are freshwater reptiles that need warm, wet environments to live. They can live in areas with short periods of cold but cannot stand long, harsh winters. They can eat a wide variety of prey (fish, turtles, small/medium mammals, etc.) and can move from water source to water source. They can live for short periods in saltwater but need freshwater long term.

Which type of habitat would the alligator survive well in, and why?

Answer

An alligator needs warmer weather and can only survive short periods of cold. It also needs access to freshwater and prefers to be in the water for a majority of its time. Due to these specific requirements, it would be best suited to survive well in a swamp. A swamp is very wet and has access to fresh water year-round. Many wetlands are located in warm climates and would provide the alligator with shelter and plenty of hunting opportunities.

Question

Barrel Cactus - The barrel cactus is large and shaped like a barrel with spines and small flowers. The plant can reach up to seven feet tall. It likes to be in the full sun and only needs to be watered occasionally. It holds water in its thick base so it can go long periods without needing rain. It has thorns to keep predators from making holes and drinking the water it has stored.

Which habitat would allow a barrel cactus to survive well, and is it best adapted for?

Answer

A barrel cactus would do best in a desert environment. It has adapted to go long periods without water and can store the water it collects within its stem. It would not do well in a rainforest or swamp because they are too wet, and plants can get too much water. A tundra is icy and frozen and does not support plant life year-round.

Question

Which organisms listed would survive well in a desert environment?

Answer

The desert is made entirely of sand. It rarely rains and is very dry. There are only a few plants, and they have small leaves. The sand is scorching and moves every time it is touched; when the wind blows, the sand shifts in all directions. Organisms that live in this type of habitat and survive well must be adapted to these conditions. A saguaro cactus, camel, scorpion, and lizard are all organisms that have variations in their behaviors and physical traits that allow them to survive in such a harsh environment.
